[0051] Guide shaft fixing seats 39 are fixedly provided at the bottom of both ends of the first mounting bottom plate 33. Lower limit seats 40 are further provided at the top of both ends of the third mounting bottom plate 34. The two lower limit seats 40 are respectively arranged on the sides away from each other of the two second screw rod fixing seats 38. The lifting device further includes a first guide shaft 11. The first guide shaft 11 extends along the first direction. The top end and the bottom end of the first guide shaft 11 are fixedly connected to the guide shaft fixing seat 39 and the lower limit seat 40 respectively;

[0052] The lifting device further includes two second mounting bottom plates 6 arranged in parallel. The second mounting bottom plates 6 are arranged between the first mounting bottom plates 33 and the third mounting bottom plates 34 and are arranged parallel to the first mounting bottom plates 33. First screw rod nuts 41 and first linear bearings 42 are fixedly provided at both ends of the second mounting bottom plates 6. The first screw rod nuts 41 are threadedly sleeved on the first screw rods 7, and the first linear bearings 42 are slidably sleeved on the first guide shafts 11;

[0053] The top end of the first lead screw 7 penetrates through the first lead screw fixing seat 37 and extends above the first lead screw fixing seat 37, and is key-connected to a transmission wheel 8. The lifting device further includes a first motor 9 and a motor mounting seat 43. The motor mounting seat 43 is correspondingly arranged for one of the transmission wheels 8 and is fixedly installed on the top of the first mounting base plate 33. The first motor 9 is fixedly arranged on the top of the motor mounting seat 43. The first motor 9 has a first motor shaft. The first motor shaft movably penetrates through the top of the motor mounting seat 43 along the first direction and is connected to a coupling 44. The coupling 44 is connected to the first lead screw 7. The four transmission wheels 8 are drivingly connected through a transmission belt 10. And a tensioning wheel 57 is arranged on the top of the first frame through a tensioning wheel mounting seat 58, which is in contact with the transmission belt 10 for adjusting the tension of the transmission belt 10;

[0054] Driven by the first motor 9, the first motor shaft rotates to drive the transmission wheel 8 connected thereto to rotate. Through the driving connection of the transmission belt 10, the four transmission wheels 8 rotate simultaneously in the same direction, so that the four first lead screws 7 rotate synchronously, and further the two second mounting base plates 6 can move simultaneously and synchronously along the first direction;

[0055] The two base connecting plates 13 of the fixing frame 12 are respectively connected to the two second mounting base plates 6, and the two base connecting plates 13 of the second bracket 4 are respectively connected to the two second mounting base plates 6. Thus, when the two second mounting base plates 6 move synchronously, the fixing frame 12 and the second bracket 4 can move simultaneously. To ensure the connection stability, the fixing frame 12 and the second bracket 4 are connected by four third connecting plates 45. The four third connecting plates 45 are grouped in pairs and are respectively arranged at the top and bottom of the fixing frame 12. The third connecting plate 45 extends along the third direction and its two ends are respectively connected to the fixing frame 12 and the second bracket 4 (as Figure 3 ).

[0056] As Figure 4 and Figure 5 shown, the first adjusting device includes four first adjusting parts. The four first adjusting parts are grouped in pairs and are respectively arranged at the top and bottom of the first bracket 3. The first adjusting part includes three first hanger fixing seats 14. The three first hanger fixing seats 14 are respectively fixedly arranged on the top of the fixing frame 12, the first bracket 3 and the second bracket 4;

[0057] The first adjusting part further includes a second lead screw 15 and a second guide shaft 16 extending along the third direction. The two ends of the second lead screw 15 are respectively rotatably connected to the first hanger fixing seat 14 of the fixing frame 12 and the first hanger fixing seat 14 of the second bracket 4. A second lead screw nut 46 is arranged on the first hanger fixing seat 14 of the first bracket 3, and the second lead screw 15 is threadedly sleeved with the second lead screw nut 46;

[0058] The two ends of the second guide shaft 16 are respectively fixedly connected to the first hanger fixing seat 14 of the fixing frame 12 and the first hanger fixing seat 14 of the second bracket 4. The first hanger fixing seat 14 of the first bracket 3 is also provided with a second linear bearing 47. The second guide shaft 16 and the second linear bearing 47 are slidably sleeved.

[0059] One end of the second screw rod 15 close to the fixing frame 12 is coaxially fixedly connected with the first synchronous sprocket 48, and the four first synchronous sprockets 48 are transmission-connected by the first synchronous chain 59, and one end of the second screw rod 15 close to the fixing frame 12 extends through and extends to the other side of the first hanger fixing seat 14 of the fixing frame 12, and is connected with a second motor (not shown in the figure);

[0060] By starting the second motor, the second screw rod 15 connected thereto can be driven to rotate, thereby rotating the first synchronous sprocket 48. Driven by the first synchronous chain 59, the four first synchronous sprockets 48 rotate synchronously at the same time, thereby moving the first bracket 3 along the third direction, so that the first bracket 3 can be close to or away from the second bracket 4.

[0061] One end of the second screw rod 15 close to the second bracket 4 is fixedly sleeved with a width adjustment fixing sleeve 49, which can limit the first hanger fixing seat 14 of the first bracket 3 to avoid excessive movement of the first bracket 3 and cause collision.

[0062] like Figure 6 and Figure 7 As shown, the horizontal conveying device includes two conveying parts which are parallel and symmetrically arranged, and the two conveying parts are respectively arranged on the side away from the first bracket 3 and the second bracket 4, and one of the conveying parts is located between the first bracket 3 and the fixed frame 12, and the conveying part includes a guide rail 17, and a plurality of transmission sprockets 18 are arranged along the length direction of the guide rail 17 on the side walls away from the two guide rails 17, and a plurality of transmission rods 19 are arranged on the side walls close to the two guide rails 17, and one end of the transmission rod 19 close to the transmission sprocket 18 movably penetrates the guide rail 17 and is coaxially fixedly connected to the transmission sprocket 18, and the connection method can be a key connection;

[0063] It should be noted that the transmission part is a segmented structure, including a first transmission section 50 and a second transmission section 51 arranged along the second direction, the first transmission section 50 has a first input end and a first output end, the second transmission section 51 has a second input end and a second output end, the first output end is close to the second input end, and a third motor 20 is arranged on the side walls close to the two first input ends and the side walls close to the two second output ends. The third motor 20 has a third motor shaft, the third motor shaft movably penetrates the guide rail 17 and is coaxially fixedly connected to a driving sprocket 21, the chain is meshed and connected to the driving sprocket 21 and the transmission sprocket 18 (not shown in the figure), and a chain pressure plate 22 is arranged above the chain to prevent the chain from de-toothing;

[0064] The guide rail 17 is provided with adjustment holes, in which a shaft rod is arranged, and a tensioning sprocket 23 is arranged on the shaft rod. The tensioning sprocket 23 meshes with the chain and is used to adjust the tension of the chain.

[0065] By starting the third motor 20, the rotation of the third motor shaft drives the rotation of the driving sprocket 21. Under the driving action of the chain, the tensioning sprocket 23 and the driving sprocket 18 rotate, and the rotation of the driving sprocket 18 drives the rotation of the driving rod 19, so as to drive the tray 2 to move.

[0066] Chain baffles 52 are arranged at both the first input end and the second output end, which can prevent safety accidents during feeding and discharging, and can protect the exposed components.

[0067] The two conveying parts can move towards each other along the third direction under the drive of the second adjusting device. Specifically, the second adjusting device includes two second adjusting parts, which are respectively arranged on the first conveying section 50 and the second conveying section 51.

[0068] Specifically, as Figure 8 shown, the second adjusting part includes two T-shaped fixing seats 24 and two second hanger fixing seats 25. The two T-shaped fixing seats 24 are respectively fixedly arranged on the tops of the two guide rails 17, and the two second hanger fixing seats 25 are fixedly arranged on the structural body 1.

[0069] The second adjusting part further includes a bidirectional lead screw 26, which extends along the third direction. The two ends of the bidirectional lead screw 26 are respectively rotatably connected to the two second hanger fixing seats 25. Third lead screw nuts 53 are arranged on the two T-shaped fixing seats 24, and the bidirectional lead screw 26 is threadedly sleeved with the two third lead screw nuts 53.

[0070] The second adjusting part further includes a third guide shaft 27, which extends along the third direction. The two ends of the third guide shaft 27 are respectively fixedly connected to the two second hanger fixing seats 25. Third linear bearings 54 are also arranged on the two T-shaped fixing seats 24, and the third guide shaft 27 is slidably sleeved with the two third linear bearings 54.

[0071] Both ends of the bidirectional lead screw 26 of each second adjustment part penetrate through the second hanger fixing seat 25 and extend, and are coaxially and fixedly connected with second synchronous sprockets 55. The second synchronous sprockets 55 on the same side of the two second adjustment parts are connected by a second synchronous chain. One of the second synchronous sprockets 55 is connected with a fourth motor. Thus, by starting the fourth motor, the second synchronous sprocket 55 connected thereto is driven to rotate, so that the bidirectional lead screw 26 rotates. Driven by the second synchronous chain, the two bidirectional lead screws 26 rotate simultaneously and synchronously, so that the four second synchronous sprockets 55 rotate synchronously, thereby driving the T-shaped fixing seats 24 of the two guide rails 17 to move towards each other, and further enabling the two conveying parts to move towards each other. When the two conveying parts approach each other, the transmission rod 19 can move from the gap between the two support bars 28 into the support space;

[0072] Further, both ends of the third guide shaft 27 are fixedly sleeved with limit fixing sleeves 56 to prevent the T-shaped fixing seat 24 from moving excessively and colliding.

[0073] Working principle: When in use, first, the two conveying parts are separated from each other through the second adjustment device, and then according to the width of the used tray 2, the first bracket 3 is adjusted through the first adjustment device to move the first bracket 3 in the third direction until the width of the support space formed between the first bracket 3 and the second bracket 4 is adapted to the width of the tray 2. Then, the support device is driven to move in the first direction through the lifting device. Preferably, the support device rises under the drive of the lifting device until the transmission rod 19 of the conveying part and the lowermost support block 5 are basically on the same horizontal plane, and the transmission rod 19 is slightly higher than the support block 5. Then, the two conveying parts are made to approach each other through the second adjustment device until the transmission rod 19 moves into the support space. Then, the tray 2 and the product to be cured thereon are placed at the first input end of the first conveying section 50. By starting the horizontal conveying device, the tray 2 and the product to be cured thereon are driven to move in the second direction along the rotating transmission rod 19 and enter the lowermost bearing space from the feeding port. When the tray 2 and the product to be cured thereon completely enter the lowermost bearing space, the two conveying parts are separated from each other through the second adjustment device, and the transmission rod 19 is disengaged from the support space, so that the tray 2 and the product to be cured thereon can fall onto the support block 5;

[0074] Afterwards, the lifting device drives the supporting device to move downward, so that the lower supporting block 5 and the driving rod 19 of the conveying part are basically on the same horizontal plane, and the driving rod 19 is slightly higher than the supporting block 5. Then, the two conveying parts are brought closer to each other through the second adjusting device until the driving rod 19 moves into the supporting space. Place the subsequent tray 2 and the product to be cured thereon at the first input end of the first conveying section 50. The tray 2 and the product to be cured thereon are conveyed to the bearing space of this layer through the horizontal conveying device. Then, the two conveying parts are moved away from each other, and the driving rod 19 disengages from the supporting space. The tray 2 and the product to be cured thereon can fall onto the supporting block 5. Proceed in this way until all the trays 2 and the products to be cured enter the interior of the supporting space;

[0075] When all the products to be cured are cured, the two conveying parts are brought closer to each other through the second adjusting device, and the driving rod 19 enters the uppermost bearing space. The horizontal conveying device conveys the uppermost tray 2. The tray 2 moves from the discharge port to the second output end and then unloads the goods. Then, the two conveying parts are moved away from each other, and the driving rod 19 disengages from the supporting space. The lifting device drives the supporting device to move upward, and the driving rod 19 enters the bearing space of the next layer to convey the tray 2 in this bearing space until all the trays 2 are completely conveyed.

[0076] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
